Patent GB-949415-A (GB)
Abstract: 949,415. Feeding webs. CROSFIELD ELECTRONICS Ltd. Nov. 23, 1962 [Nov. 24, 1961], No. 42140/61. Heading B6B. [Also in Division G3] In an arrangement for ensuring correct registration between a moving web 1 and a number of machines 2 . . . 4 in a multi-colour printing unit, pulses corresponding to the position of printing cylinders are recorded on a narrow strip of magnetic ink printed on the underside of the web at 7 and detected at reproducing heads 11, 12; variations in the time between these two events are detected by devices 14, 15 and used to adjust the path length between successive machines by vertical movement of rollers 5, 6. An impulse wheel 10 driven from the printing cylinders produces several pulses per revolution and the web length from recording to each reproducing head is preferably arranged to contain an exact number of recorded pulses when registration is correct so that the reproduced signals are in synchronism with those from the impulse wheel 10. Lack of synchronism, e.g. due to stretching of the web, results in a correcting signal to servomotors 16, 17, preferably derived in the manner described in Specification 641,830. The web is kept in tension by making each successive printing cylinder of slightly greater circumference than its predecessor and driving them all at the same speed.

Title: Plant monitoring system
Inventor: CROWTHER GEOFFREY
IPC: G05B23/02
Filed: 1995-03-01
Abstract: A monitoring system 10 for a plant comprises means 14, 16, 18 for supplying a sequence of data signals and test signals 24 to a signal analyser 20. The analyser 20 produces a sequence of status signals indicating whether, according to the signals it receives, the plant is in an acceptable or an unacceptable state. The status signals are supplied to a deciphering unit 30 such as an exclusive-or gate to which are also supplied key signals 32, such that the deciphering unit 30 should produce output signals forming a recognisable pattern. If the pattern is not observed then either the monitoring system 10 or the plant is malfunctioning. The sequence of data and test signals is not constrained by the requirement to produce the desired pattern.   <IMAGE>

Title: Sunbeds
Inventor: MARSHALL BRIAN DENNIS
IPC: A61N5/00
Filed: 1995-04-28
Abstract: A sunbed comprises a multiplicity of ultra-violet emitting tubes (9) each of which is located in a respective enclosure (10) defined between the front sheet (7) of the sunbed and a reflector (8). Fans (12) are provided for blowing cooling air through apertures or nozzles in the reflector into the enclosures (10) to cool the tubes. The temperature of the tubes is monitored and the rate of flow of air is adjusted to maintain the tubes at optimum operating temperature. The optimum operating temperature may vary with the life of the tube so that the tubes are run hotter as they age in order to maintain a desired level of UV output. Preferably, additional sensors are provided to shut down the sunbed if levels of UV-C output rise above a pre-determined level or if the temperature of the sunbed rises above a pre-determined level. Preferably, a key switch control safety timer is provided for preventing re-setting of the standard timer immediately after one period of use.

Title: Condensing boiler heat exchanger
Inventor: CRITCHLEY NICHOLAS JOHN
IPC: F24H1/28
Filed: 1995-08-15
Abstract: A fully condensing heat exchanger for a boiler, has a vertical cylindrical water jacket 1. Tubes 4 of an oblong section pass vertically through the water jacket 1. The flue gases or products of combustion pass through these tubes in such a way that the hottest part of the flue gases is within the portion of the tubes in the hottest part of the water way. The coolest part of the flue gases is within the portion of the tubes in the coolest part of the water way. Condensation forms in the lower section 3 of the heat exchanger. Because all of the heat transfer happens within the tubes 4 there is no separate or additional baffle required to deflect the flue gases against the water jacket. A single piece lid 13 allows access to both combustion chamber 11 and tubes 4.

Title: Routing tube for optical fibre and cable
Inventor: HODGE KENNETH GEORGE
IPC: F16L11/08
Filed: 1995-11-21
Abstract: A routing tube 7 for one or more optical fibres 2 or optical fibre cables comprises an extruded hollow plastics inner tube 21, an extruded hollow plastics outer tube 24 that encloses the inner tube and is bonded thereto, and, sandwiched between the inner and the outer tube, a non-metallic strength member 23 which extends along the length of the routing tube but extends circumferentially over a minor part only of the inner tube e.g up to 90 DEG  but preferably 5 to 20 DEG  and is bonded to the inner and the outer tube by a hot-melt adhesive 22. The inner and outer tubes may be of low density polyethylene and the member 23 of aramid fibre. Since the routing tube is manufactured entirely from non-metallic elements, it can be routed in the vicinity of high voltage power lines with no risk to safety if it touches the power line. <IMAGE>

Title: Electric vehicle - guide wheel spring biassed away from drive wheel
Inventor: LOPEZ ALBA ADELARDO
IPC: B61C13/04
Filed: 1996-02-16
Abstract: Vehicle 1 is driven along a rail 4 by motor 5 and drive wheel 2. Guide wheel 6 acts on rail 14, and is frictionally driven by drive wheel 2 (fig.2). Wheel 6 floats on component 8, and is biassed forward by spring 9. Shaft 7 of wheel 6 rests in an elongate slot in lever 10. The lever is pivoted at point 11, and is biassed upwards by spring 12. The rotation of the lever is limited by stop 13. When guide wheel 6 contacts guide rail 14, both springs are compressed, and wheels 2 and 6 touch. Consequently, contact between the wheels occurs only when the vehicle is moving underneath the guide rail. Elsewhere, there is no contact between the wheels, and thus less wear on their circumferences.

Title: Underground leak location
Inventor: HARPER MARK FRANCIS LUCIEN
IPC: G01M3/24
Filed: 1997-06-10
Abstract: The location of a leak 1 in an underground fluid-carrying pipe 2 is determined by locating on the ground surface in the vicinity of the leak either an array of ground-movement detection sensors 3 or a single such sensor at a plurality of positions and processing the signals from the sensors to calculate the leak location. Each sensor 3 comprises a geophone supported in a lower polymer mat (12, Fig.4) by a plurality of polymer annuli (14). A support block (15) attaches the geophone to an upper polymer mat (13), the two mats being separated by an open cell plastic foam layer (17). Such an arrangement holds the geophone in ground contact and provides damping so as to avoid significant mounting resonance effects between the geophone and the ground.

IPC: G01J3/45
Filed: 1998-02-05
Abstract: A method of determining a filter to compensate for the response characteristics of the sensor in a fourier transform spectrometer comprising a) Recording of a broad-band effective interferogram, carrying out complex Fourier transformation, formation of the mean value of the phase spectra and conversion of the abscissa values into electrical frequencies; b) Establishing the transfer function of the detector and of the further signal processing elements, wherein the free parameters of the transfer function are chosen such that the phase response of the transfer function deviates as little as possible from the mean value of the phase spectrum of the effective interferogram recorded according to step (a). c) If necessary digitization of the transfer function determined according to step (b); and d) Determination of the compensation filter as the inverse of the discrete transfer function. In this way a deconvolution of the transfer function of the signal processing elements from the spectra is rendered possible with means as simple as possible and in a particularly effective manner.
